How to find port and slot ID by index port ID shown in name server on SAN Brocade Director

When you wanna find out physical port location - slot and port ID by WWN in name server you can see just index port ID and Port# which is not as same ID as physical port ID.

If you know Index port # or port ID gathered in name server you can link it with slot and port ID by using switchshow command:

42 is index port ID, 3 is slot ID and 10 is physical port ID

SAN:admin> switchshow | grep " 42"
Index Slot Port Address Media Speed State     Proto
 42    3   10   642a00   id    N4   Online           F-Port  10:00:00:00:00:00:00:01

AIX / VIOS CDP - Cisco Discovery Protocol to gather information about port on CISCO switch

The Cisco Discovery Protocol (CDP) is a proprietary Data Link Layer network protocol developed by Cisco Systems. It is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address.

Device connected to CISCO CDP enabled switch can sniff CDP packets and gather inflormation about port like switch name, trunk and VLAN IDs, port number like Gi1/5.

VMware support it by default and it can be seen in GUI in networking tab.

AIX / VIOS doesn't support that by default but it can be gathered by script using tcpdump.

Script for CDP on AIX can be downloaded here:
